CREATE SCHEMA#

Synopsis#

CREATE SCHEMA [ IF NOT EXISTS ] schema_name
[ AUTHORIZATION ( user | USER user | ROLE role ) ]
[ WITH ( property_name = expression [, ...] ) ]

Description#

Create a new, empty schema. A schema is a container that holds tables, views and other database objects.

The optional IF NOT EXISTS clause causes the error to be suppressed if the schema already exists.

The optional AUTHORIZATION clause can be used to set the owner of the newly created schema to a user or role.

The optional WITH clause can be used to set properties on the newly created schema. To list all available schema properties, run the following query:

SELECT * FROM system.metadata.schema_properties
